Definitions
- the present invention relates to diene elastomer compositions reinforced with an inorganic filler, which can be used for the manufacture of tires or semi-finished products for tires, in particular treads for these tires.
- carbon black exhibits such aptitudes, which is generally not the case for inorganic fillers. Indeed, for reasons of reciprocal affinities, the particles of inorganic charge have an unfortunate tendency, in the elastomeric matrix, to agglomerate between them. These interactions have the harmful consequence of limiting the dispersion of the filler and therefore the reinforcing properties to a level substantially lower than that which would theoretically be possible to achieve if all the bonds (inorganic filler / elastomer) capable of being created. during the mixing operation, were actually obtained; on the other hand, these interactions tend to increase the consistency in the raw state of the rubber compositions and therefore to make their implementation ("processability") more difficult than in the presence of carbon black.
- Such rubber compositions comprising reinforcing inorganic fillers of the siliceous or aluminous type, have for example been described in the patents or patent applications EP-A-0501227 (or US-A-5227425), EP-A-0735088 (or US-A-5852099), EP-A- 0810258 (or US-A-5900449), EP-A-0881252, WO99 / 02590, WO99 / 02601, WO99 / 02602, WO99 / 28376, WOOO / 05300, WO00 / 05301.
- compositions exhibiting such a compromise of contradictory properties are also described in applications EP-A-0810258 and WO99 / 28376, with, as reinforcing inorganic fillers, specific aluminous fillers (aluminas or (oxide) hydroxides)) high, or in applications WO00 / 73372 and WO00 / 73373 describing specific titanium oxides of the reinforcing type.
- aluminous fillers aluminas or (oxide) hydroxides
- a coupling agent also called a bonding agent, which has the function of ensuring the bond between the surface of the particles of inorganic filler and the elastomer, while facilitating the dispersion of this filler inorganic within the elastomeric matrix.
- coupling agent inorganic filler / elastomer

- compositions are produced in suitable mixers, using two successive preparation phases well known to those skilled in the art: a first working or thermo-mechanical kneading phase (sometimes called a "non-productive" phase) at high temperature, up to a maximum temperature (noted T max ) of between 110 ° C and 190 ° C, preferably between 130 ° C and 180 ° C, followed by a second phase of mechanical work (sometimes referred to as the "productive" phase) at a lower temperature, typically less than 110 ° C, for example between 40 ° C and 100 ° C, finishing phase during which the crosslinking or vulcanization system is incorporated; such phases have been described for example in the applications EP-A-0501227, EP-A-0735088, EP-A-0810258, EP-A-0881252, WO99 / 28376, WOOO / 05300 or WOOO / 05301 mentioned above.
- a first working or thermo-mechanical kneading phase (sometimes called
- the process for manufacturing the compositions according to the invention is characterized in that at least the reinforcing inorganic filler and the hydroxysilane coupling agent are incorporated by kneading with the diene elastomer during the first so-called non-productive phase, c '' that is to say that one introduces into the mixer and that one thermomechanically kneads, in one or more stages, at least these different basic constituents until reaching a maximum temperature of between 110 ° C and 190 ° C, preferably between 130 ° C and 180 ° C.
- the first (non-productive) phase is carried out in a single thermomechanical step during which all the necessary basic constituents, any agents, are introduced into a suitable mixer such as a conventional internal mixer. covering or additional processing and other various additives, with the exception of the vulcanization system.
- a second thermomechanical working step can be added to this internal mixer, after the mixture has fallen and intermediate cooling (cooling temperature preferably less than 100 ° C.), with the aim of subjecting the compositions to a complementary thermomechanical treatment, in particular to improve still the dispersion, in the elastomeric matrix, of the reinforcing inorganic filler and of its coupling agent.
- the total duration of the kneading, in this non-productive phase is preferably between 2 and 10 minutes.
- the vulcanization system is then incorporated at low temperature, generally in an external mixer such as a cylinder mixer; the whole is then mixed (productive phase) for a few minutes, for example between 5 and 15 minutes.
- the final composition thus obtained is then calendered, for example in the form of a sheet, a plate or even extradited, for example to form a rubber profile used for the manufacture of semi-finished products such as treads, crown plies, sidewalls, carcass plies, heels, protectors, air chambers or internal rubber compounds for tubeless tires.
- Vulcanization (or baking) is carried out in a known manner at a temperature generally between 130 ° C and 200 ° C, for a sufficient time which can vary for example between 5 and 90 min depending in particular on the baking temperature, the system of vulcanization adopted, of the vulcanization kinetics of the composition considered or of the size of the tire.
- the vulcanization system proper is preferably based on sulfur and a primary vulcanization accelerator, in particular an accelerator of the sulfenamide type.
- a primary vulcanization accelerator in particular an accelerator of the sulfenamide type.
- various known secondary accelerators or activators of vulcanization such as zinc oxide, stearic acid, derivatives guanidiques (in particular diphenylguanidine), etc.
- Sulfur is used at a preferential rate of between 0.5 and 10 phr, more preferably of between 0.5 and 5.0 phr, for example between 0.5 and 3.0 phr when the invention is applied to a strip. tire bearing.
- the primary vulcanization accelerator is used at a preferential rate of between 0.5 and 10 phr, more preferably between 0.5 and 5.0 phr in particular when the invention applies to a tire tread.
- the invention relates to the rubber compositions described above both in the so-called “raw” state (ie, before baking) and in the so-called “cooked” or vulcanized state (ie, after crosslinking or vulcanization). .
- compositions in accordance with the invention can be used alone or as a blend (i.e., as a mixture) with any other rubber composition which can be used for the manufacture of tires.
- the invention is implemented with a bis- (propyldimethylsilanol) polysulfide of particular formula (II-2):
- the first stage consists of an alcoholysis making it possible to replace the chlorine carried by the silicon atom of product A by an ethoxyl group (EtO) of ethanol, this reaction being carried out in the presence of triethylamine intended to trap the hydrochloric acid released during the reaction.
- EtO ethoxyl group
- a 2 L three-necked flask (liter) (previously dried in an oven for 24 h), surmounted by a condenser and fitted with magnetic stirring, 950 mL of ethanol (Normapur grade) is introduced under a stream of argon ) then 288 mL of triethylamine (2.07 mol or 209 g) using a syringe.
- the ice bath is removed while the stirring is continued at room temperature overnight, under a stream of argon.
- the GC analysis gas chromatography shows the disappearance of the peak corresponding to the starting product A and the formation of chloropropyl-dimethylethoxysilane (product B).
- the reaction medium is then filtered through an Alhin tube in order to separate product B in solution in ethanol from triethylamine hydrochloride.
- the filtrate containing product B is concentrated and then distilled under vacuum (2 mm Hg; oil bath temperature 70 ° C; temperature at the top of the column 45 ° C), in order to remove the excess of free triethylamine and isolate product B in a pure state.
- This second step consists in hydrolyzing the above ethoxysilane (in solution in methanol) so as to obtain the hydroxysilane.
- This reaction is carried out by the action of an aqueous NaOH solution; after reaction, the excess base initially introduced is neutralized by potassium dihydrogen phosphate.
- the solution obtained which has a pH equal to 7, is stirred for a few minutes before being placed in the presence of 200 ml of ether intended to extract the product C formed.
- the biphasic medium is then subjected to stirring, for approximately 30 to 45 min, then introduced into a separatory funnel.
- the isolated organic phase is washed once with water and then dried over MgSO 4 before being filtered and then concentrated in vacuo.
- the CPG chromatogram of the crude reaction product thus collected then has three peaks which can be attributed respectively to (i) chloropropyl-dimethylmethoxysilane, probably resulting from the reaction of methanol on product B (of the order of 2% in d units '' after 1H NMR), to (ii) product C targeted, largely majority (85% in units according to 1H NMR), as well as to (iii) bis (chloropropyl) -tetramethyldisiloxane (present at 13% in units ).
- Vacuum distillation carried out in a ball oven (Kûgelrohr), makes it possible to isolate product C.
- the temperature of the oven is preferably chosen below 45 ° C, to limit any risk of seeing the product C condense to the corresponding disiloxane.
- product C is isolated under a vacuum of 1 mbar by heating to 40 ° C; bis (chloropropyl) -tetramethyldisiloxane due to its higher boiling temperature remains in the distillation flask. 2.48 g of a pure colorless liquid are thus isolated, the NMR and mass spectrometry analyzes confirm the production of product C corresponding to the following formula:
- the sodium polysulfide generated by insertion of sulfur in sodium sulfide Na 2 S in an aqueous medium, comes to replace the chlorine atom of two molecules of product C in solution in toluene.
- the reaction is carried out in the presence of a phase transfer catalyst (TBAB) and sodium chloride NaCl. 3.50 g (i.e. 14.5 mmol) of Na 2 S. 9H 2 O and 1.40 g (i.e. 43.5 mm) are introduced into a 250 ml three-necked flask, topped with a condenser and fitted with a magnetic stirrer.
- TBAB phase transfer catalyst
- NaCl sodium chloride
- reaction medium is then transferred to a separating funnel so as to isolate the toluene phase, which is dried over magnesium sulfate after having been washed with water.
- organic solution is then filtered and taken up in ether before being distilled in a ball oven (40 ° C), in order to remove the residual chloropropyl-dimethylsilanol (product C).
- the disulfide S 2 level determined by NMR, is equal to approximately 18% of the polysulfide units.
- This product therefore consists, as is the case in particular for alkoxysilane polysulfides such as TESPT, of a distribution of polysulfides whose average value of x is close to 4. It will be understood that modified synthesis conditions would allow d '' obtain other distributions of polysulphides, with mean values of x variable but preferably between 2 and 6, more preferably within a range of 2 to 4.
- a diene elastomer (or mixture of diene elastomers) is introduced into an internal mixer, filled to 70% and whose initial tank temperature is approximately 60 ° C. , if applicable), the reinforcing filler, the coupling agent, then the various other ingredients with the exception of the vulcanization system.
- Thermomechanical work (non-productive phase) is then carried out in one or two stages (total mixing time equal to approximately 7 min), until a maximum "fall" temperature of approximately 165 ° C is reached.
- the mixture thus obtained is recovered, cooled, then sulfur and sulfenamide accelerator are added to an external mixer (homo-finisher) at 30 ° C, mixing everything (productive phase) for 3 to 4 minutes.
- compositions thus obtained are then calendered in the form of plates (thickness of 2 to 3 mm) or of thin sheets of rubber for the measurement of their physical or mechanical properties, or extruded to form profiles which can be used directly, after cutting and / or assembly to the desired dimensions, for example as semi-finished products for tires, in particular as tire treads.
- composition C-1 TESPT
- composition C-2 product D synthesized above.
- the two organosilanes tested are used at a rate of less than 8 phr, this amount representing less than 10% by weight relative to the amount of reinforcing inorganic filler.
- the TESPT is bis (3-triethoxysilylpropyl) tetrasulfide, of formula [(C 2 H 5 O) 3 Si (CH) 3 S] 2 ; it is marketed for example by the company Degussa under the name "Si69” (or "X50S" when supported at 50% by weight on carbon black), or by the company Witco under the name "Silquest A1289" (in both cases, commercial mixture of polysulphides S x with an average value for x which is close to 4).
- the developed formula of TESPT is:
- Tables 1 and 2 give the formulation of the two compositions (Table 1 - rate of the various products expressed in pce), their properties before and after cooking (approximately 30 min at 150 ° C); the vulcanization system consists of sulfur and sulfenamide.
- the two compositions tested also contain (not indicated in Table 1) a small proportion of carbon black N330 (6 phr) used as a black pigmentation agent and anti-UV.
- Figures 1 and 2 attached respectively reproduce the rheograms (torque in dN.m as a function of the vulcanization time in min) and the modulus curves (in MPa) as a function of the elongation (in%); these curves are denoted Cl and C2 in FIG. 1, then Cl 'and C2' in FIG. 2, and they correspond respectively to compositions C-1 and C-2.
- composition of the invention C-2 shows a shorter roasting time than that of the control composition C-1, but this time T5 remains sufficient to provide a satisfactory margin of safety with regard to the roasting problem;
- composition C-2 the Mooney plasticity values remain low (85 to 90 MU) in all cases, the lowest value being moreover recorded on the composition C-2; this is an indicator of a very good ability of the compositions of the invention to be used in the raw state, at least as good as that of conventional compositions using alkoxysilane polysulfides;
- the composition of the invention C-2 compared with the control composition, has modulus values under strong deformation (Ml 00 and M300) and a ratio
- the composition of the invention is unexpectedly distinguished by a conversion speed constant K which is more than twice higher than that of the control composition; in other words, the composition can be cooked in a much shorter time.
- the rheograms of FIG. 1 appended confirm the superiority of the composition of the invention C-2: induction time close to that of the control composition; maximum torque identical to that of the control composition, but reached in a much shorter time; higher conversion rate constant K.
- Figure 2 also confirms the previous observations: the curve C2 '(composition C-2) and the curve Cl' (control composition Cl) are almost identical, in particular for the largest elongations which are representative of the reinforcement and therefore of the ability of rubber compositions to resist wear.
- composition C-2 of the invention illustrates not only a high quality of the bond (or coupling) between the reinforcing inorganic filler and the diene elastomer, at least equal to that available with polysulphides d 'usual alkoxysilanes such as TESPT, but also, unexpectedly, a much improved vulcanization ability.
- the invention finds particularly advantageous applications in rubber compositions which can be used for the manufacture of tire treads having both a low rolling resistance and a high resistance to wear, in particular when these treads are intended tires for passenger vehicles or for industrial vehicles of the Truck type.
